NOTE
Status: Active research — This document catalogs terms that have different meanings across typological systems. Using these terms requires explicit qualification.

Rationale

Different typological systems developed independently, often using the same words for different constructs. This creates confusion when mapping between systems or building unified models. This document identifies critical conflicts and provides disambiguation rules.

Critical Conflicts

CONFLICT-1: Extraversion — Five Distinct Meanings

System Construct Definition Basis
Jung (1921) Attitude type Direction of psychic energy (libido) Qualitative
Eysenck (PEN) Factor Cortical arousal level Biological: low arousal → seeks stimulation
Big Five Factor (OCEAN E) Sociability, activity, positive affect Factor analysis
MBTI Dichotomy E vs I directional preference Simplified Jung
Socionics Type attitude + element polarity Type-level E/I exists, and i/e also marks information elements Mixed: type-level and element-level

Key Insight: These are NOT the same construct. "Extraversion" in Eysenck refers to biological arousal, while in Jung it refers to psychic energy direction. Both are labeled "E" but have different theoretical foundations.

Disambiguation Rule:

  • Always specify: "Jungian extraversion", "Eysenckian extraversion", "Big Five Extraversion"
  • For Socionics: type-level E/I is valid, but clarify that Socionics E/I is not interchangeable with MBTI E/I

Example:

# Confusion:
mbti: "ENTP"  # MBTI extraversion
socionics: "ILE"  # often mapped to ENTP, but only approximately
# Socionics does use E/I terminology, but not identically to MBTI

CONFLICT-2: Function — Three Distinct Meanings

System Construct Definition
Jung/Socionics Psychic function Unit of information processing (8 elements)
Psychosophy Aspect Will, Emotion, Logic, Physics
Big Five Facet Sub-trait within main factor

Disambiguation Rule:

  • Socionics: "psychic function" or element name (Te, Ti, etc.)
  • Psychosophy: "psychosophy aspect" or "function position"
  • Big Five: "facet" or "sub-trait"

---

CONFLICT-3: Introversion — Two Distinct Meanings

System Construct Inverted Meaning
Jung/MBTI Attitude Energy directed inward
Socionics Type attitude + element polarity Socionics has introverted types and introverted elements, but the construct is not identical to MBTI

Critical Problem: In MBTI, INTJ = introverted. In Socionics, a type may also be called introverted, but it still contains both introverted and extraverted information elements. The shared label hides different underlying theory.

Disambiguation Rule: For Socionics, it is acceptable to use type-level E/I, but clarify that Socionics introversion/extraversion is not a drop-in synonym for MBTI E/I.

CONFLICT-4: Intuition — Two Distinct Meanings

System Construct Definition
Jung/MBTI Perception function Sensing vs Intuition (S/N dichotomy)
Socionics Intuition element Ni (Time), Ne (Ideas)
Psychosophy No direct equivalent Psychosophy does not have a canonical standalone Intuition aspect

Disambiguation Rule:

  • MBTI: "intuition" = perception mode
  • Socionics: "intuition element" or specify Ni/Ne
  • Psychosophy: avoid treating "intuition" as a standard Psychosophy aspect unless a specific non-canonical school is being discussed

---

CONFLICT-5: Feeling — Two Distinct Meanings

System Construct Definition
Jung/MBTI Judgment function T vs F dichotomy
Socionics Feeling element Fi (internal), Fe (external)
Psychosophy Emotions (E) Soul/feeling function

Disambiguation Rule: MBTI Feeling and Socionics Fe/Fi are related only loosely. Any mapping between them should be treated as approximate.

---

CONFLICT-6: Sensing — Two Distinct Meanings

System Construct Definition
Jung/MBTI Perception function S vs N dichotomy
Socionics Sensing element Si (comfort), Se (will)
Psychosophy Physics (F) Attitude to the physical/material domain, including comfort, resources, and bodily reality

System-Specific Terminology Gaps

Terms That Exist in One System But Not Others

System Unique Term Other Systems
Socionics Model A, Block structure No direct equivalent
Socionics Quadra (4 groups) No equivalent
Socionics PoLR (Vulnerable function) No equivalent
Psychosophy Repression/Vagination Different constructs
Temporistics Aspect position (1-4) No direct equivalent
Big Five OCEAN acronym Different naming

Mapping Confidence Guidelines

Mapping Confidence Reason
MBTI ↔ Socionics Common but disputed Widely attempted in practice, but not a stable one-to-one mapping
Big Five ↔ MBTI Approximate only Trait vs typology constructs differ substantially
Big Five ↔ Socionics Weak direct mapping No standard direct correspondence
Psychosophy ↔ Any Exploratory Requires more research
Temporistics ↔ Any Exploratory Requires more research

---

Practical Implications

For Cross-Typology Work

  1. Never assume term equivalence — Check which system the term originates from
  2. Always qualify — Say "Socionics Fi" not just "feeling"
  3. Track confidence — Note mapping confidence in outputs
  4. Flag ambiguous — When unclear, ask for clarification or note uncertainty

For This Project

When building unified compatibility models:

  • Use Socionics as primary for information processing
  • Do not convert MBTI into Socionics; use any comparison only as a qualified terminology bridge
  • Big Five used for broad trait validation only
  • Psychosophy and Temporistics — research needed

TODO

  • [ ] Add research on Psychosophy ↔ other system mappings
  • [ ] Clarify Temporistics terminology
  • [ ] Document system-specific assessment instruments
  • [ ] Create visual terminology map
